Area forecast discussion, Jun 17, 8:39 AM MST, 5 hours 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER/BOULDER CO 939 AM MDT MON JUN 17 2013 .UPDATE... && .SHORT TERM...OVERALL MOISTURE LEVELS ARE SIMILAR TO YESTERDAY WITH PW VALUES AROUND .6" OF AN INCH OVER THE FRONT RANGE. A WEAK SURGE HAS MOVING MOVING SOUTH ACROSS THE PLAINS EARLY THIS MORNING AS WINDS HAVE SHIFTED NORTHEAST AND DEWPOINTS HAVE RISEN BACK INTO THE LOWER 50S OVER THE NORTHERN FRONT RANGE FROM ERIE NORTHWARD TO THE WYOMING BORDER. MODELS NOT DOING VERY WELL WITH THIS ESPECIALLY THE NAM. NAM SEEMS WAY TOO DRY AND WILL DISCOUNT. THE MAIN THREAT WILL STILL BE ON THE EASTERN PLAINS TODAY WITH UPPER 40S/LOWER 50S DEWPOINTS AND SURFACE BASED CAPES PROGGED FROM 1000-2000J/KG. WOULD STILL EXPECT THE LOW LEVEL MOISTURE TO MIX OUT OVER THE FRONT RANGE BUT WITH THIS WEAK SURGE MIGHT BE ABLE TO HOLD IT IN A BIT LONGER THAN MODELS INDICATE. WILL MONITOR IN CASED POPS NEED TO BE INCREASED OVER THE FRONT RANGE. WILL STILL KEEP THE MAIN SEVERE THREAT ON THE PLAINS AND EAST OF THE DENVER AREA/URBAN CORRIDOR. .AVIATION...WITH THE WEAK SURGE...SURFACE WINDS SHIFTING TO THE NORTHEAST. WINDS WILL GRADUALLY SHIFT TO A MORE EASTERLY COMPONENT THIS AFTERNOON. STILL LOOKING FOR ISOLATED STORMS LATER THIS AFTERNOON WITH GUSTY AND VARIABLE WINDS THE MAIN THREAT. IF WE CAN HOLD ONTO LOW LEVEL MOISTURE A BIT LONGER THAN STORMS MAY BE STRONGER. && .PREV DISCUSSION... /ISSUED 356 AM MDT MON JUN 17 2013/ SHORT TERM...UPPER LEVEL RIDGE WILL EXTEND FROM THE SOUTHERN ROCKIES NORTH TO THE NORTHERN ROCKIES. THIS WILL RESULT IN A WESTERLY FLOW ALOFT. AT THE SURFACE...A LOW PRESSURE TROUGH WILL BE DRAPED ACROSS CENTRAL COLORADO. THIS WILL CAUSE SURFACE WINDS TO BECOME EASTERLY AND PULL MOISTURE INTO EASTERN COLORADO. AIRMASS ABOVE THE LOW LEVEL EAST WINDS WILL BE DRY AND WILL MIXED DOWN ALONG THE FRONT RANGE THIS AFTERNOON AND CAUSE DEW POINTS TO FALL INTO TO 30S. EVEN THOUGH THE AIRMASS WILL BE DRY WEST OF I-25...STEEP MID LEVEL LAPSE RATES SHOULD TRIGGER ISOLATED TO SCATTERED SHOWERS AND STORMS. DUE TO THE LIMITED MOISTURE AND INSTABILITY...THE STORMS WILL WEAK AND PRODUCE LIGHT TO MODERATE RAINFALL AND GUSTY OUTFLOW WINDS. OVER THE EASTERN PLAINS MOISTURE WILL BE DEEPER AND DEW POINTS WILL BE ABLE TO STAY IN THE UPPER 40S TO MID 50S. THESE DEW POINTS ALONG WITH HIGHS IN THE MID 80S WILL PRODUCE CAPES OF 1000-2000 J/KG. IN ADDITION TO THE GOOD INSTABILITY...EASTERLY LOW LEVEL WINDS AND WESTERLY WINDS ALOFT WILL PROVIDE ENOUGH SHEAR TO PRODUCE A FEW SUPER CELLS. LARGE HAIL AND DAMAGING WILL BE THE MAIN THREAT WITH THE STRONGER STORMS. APPEARS THE BEST CHANCE FOR SEEING SEVERE STORMS WILL BE EAST OF A LINE FROM FORT MORGAN TO LIMON. LONG TERM...NOT MUCH CHANGE IN THE PATTERN FOR TUESDAY. THE UPPER LEVEL WESTERLY FLOW WILL BE FAIRLY WEAK WITH THE RIDGE AXIS OVER EASTERN COLORADO BY 00Z WEDNESDAY. THE MDLS MAINTAIN THE LOW LEVEL MOISTURE OVER THE NORTHEAST PLAINS OF COLORADO...WITH THE POTENTIAL FOR TSTMS IN THE AFTN AND EVENING HIGHEST EAST OF THE URBAN CORRIDOR. FAVORABLE DIRECTIONAL SHEAR AND CAPE (AT OR ABOVE 1500 J/KG0 FOR A FEW SEVERE TSTMS. TUESDAY NIGHT AND WEDNESDAY... THE UPPER RIDGE CONTINUES TO TRANSLATE EASTWARD AND THE FLOW ALOFT BECOMING DRY AND SOUTHWESTERLY. AS A RESULT...THE THREAT OF THUNDERSTORMS WILL DIMINISH WITH JUST A SLGT CHC OF THUNDERSTORMS OVER THE FAR NORTHEAST PLAINS. THE FLOW ALOFT WILL INCREASE OUT OF THE SOUTHWEST ON THURSDAY AND FRIDAY...AS A CLOSED LOW OVER THE PAC NW SLOWLY MOVES INTO THE NRN ROCKIES. CONSEQUENTLY...TEMPERATURES WILL RISE AND THE RELATIVE HUMIDITIES IN THE AFTN WILL DROP. THE END RESULT WILL BE AN ELEVATED FIRE DANGER FOR THURSDAY AND FRIDAY. AREAS OVER SOUTH PARK...THE FRONT RANGE FOOTHILLS AND PALMER DIVIDE WILL LIKELY BE THE DRIEST. THE MDLS HINT AT SOME COOLING OVER THE WEEKEND WITH THE FLOW ALOFT DECREASING. IN ADDITION...THERE IS A HINT OF SOME SUBTROPICAL MOISTURE CLIPPING SRN AND ERN PORTIONS OF CO ON SATURDAY. AS THE TROUGH OVER THE NRN ROCKIES SLIDES EASTWARD ALONG THE CANADIAN BORDER ON SUNDAY...THE MDLS ALSO INDICATE AN ASSOCIATED COLD FRONT POSSIBLY SLIPPING INTO THE NERN PLAINS AROUND 00Z MONDAY. AVIATION...WINDS WILL BECOME LIGHT AFTER 12Z AND THEY SHIFT TO THE EAST BY 18Z. ISOLATED TO SCATTERED THUNDERSTORMS WILL AGAIN DEVELOP AND BE POSSIBLE AFTER 20Z. GUSTY OUTFLOW WINDS TO 40 KNOTS WILL BE POSSIBLE WITH THE STORMS. LOW CLOUDS AND PATCHY FOG ARE OVER FAR NORTHEAST COLORADO AT THIS TIME. JUST A SLIGHT CHANCE OF THEM MOVING INTO THE DENVER AREA AND WILL LEAVE THEM OUT OF THE TAF FOR NOW. HYDROLOGY...SIMILAR CONDITIONS WILL PREVAIL AS THE LAST COUPLE OF AFTERNOONS WITH ISOLATED TO SCATTERED THUNDERSTORMS EXPECTED OVER THE BURN SCARS. AIRMASS WILL CONTINUE TO BE ON THE DRY SIDE AND THE STORMS THAT DO DEVELOP WILL BE MOVING AT 15 TO 25 MPH. THE THREAT FOR PROLONGED HEAVY RAIN OVER THE BURN AREAS WILL REMAIN CLOSE TO ZERO. && .BOU WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...ENTREKIN LONG TERM....COOPER AVIATION...ENTREKIN
